wpf datagrid样式

WPF DataGrid 可以通过样式（Style）来自定义其外观和行为。以下是一个基本的样式示例：

<Window.Resources>
    <Style TargetType="{x:Type DataGrid}">
        <Setter Property="Background" Value="White"/>
        <Setter Property="BorderBrush" Value="Gray"/>
        <Setter Property="BorderThickness" Value="1"/>
        <Setter Property="RowHeaderWidth" Value="0"/>
        <Setter Property="HeadersVisibility" Value="Column"/>
        <Setter Property="RowBackground" Value="#F0F0F0"/>
        <Setter Property="AlternatingRowBackground" Value="#E0E0E0"/>
        <Setter Property="AutoGenerateColumns" Value="False"/>
        <Setter Property="CanUserAddRows" Value="False"/>
        <Setter Property="CanUserDeleteRows" Value="False"/>
        <Setter Property="SelectionMode" Value="Single"/>
        <Setter Property="IsReadOnly" Value="True"/>
        <Setter Property="FontFamily" Value="Segoe UI"/>
        <Setter Property="FontSize" Value="12"/>
        <Setter Property="Foreground" Value="#333333"/>
        <Setter Property="GridLinesVisibility" Value="None"/>
        <Setter Property="ColumnHeaderHeight" Value="30"/>
        <Setter Property="RowHeight" Value="30"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type DataGrid}">
                    <Border x:Name="border"
                            Background="{TemplateBinding Background}"
                            BorderBrush="{TemplateBinding BorderBrush}"
                            BorderThickness="{TemplateBinding BorderThickness}"
                            Padding="2">
                        <ScrollViewer x:Name="DG_ScrollViewer"
                                      Focusable="false">
                            <Grid>
                                <Grid.RowDefinitions>
                                    <RowDefinition Height="Auto"/>
                                    <RowDefinition Height="*"/>
                                </Grid.RowDefinitions>
                                <Grid.ColumnDefinitions>
                                    <ColumnDefinition Width="*"/>
                                </Grid.ColumnDefinitions>
 
                                <DataGridColumnHeadersPresenter Grid.Row="0"
                                                                Grid.Column="0"
                                                                Margin="0,0,0,5"
                                                                x:Name="PART_ColumnHeadersPresenter"
                                                                Visibility="{TemplateBinding HeadersVisibility}"/>
 
                                <ScrollContentPresenter x:Name="PART_ScrollContentPresenter"
                                                        Grid.Row="1"
                                                        Grid.Column="0"
                                                        CanContentScroll="{TemplateBinding CanContentScroll}"
                                                        Content="{TemplateBinding Content}"
                                                        ContentTemplate="{TemplateBinding ContentTemplate}"
                                                        ContentStringFormat="{TemplateBinding ContentStringFormat}"
                                                        Focusable="false"/>
                            </Grid>
                        </ScrollViewer>
                    </Border>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</Window.Resources>

该样式定义了 DataGrid 的各种属性和行为，例如背景、边框、行高、列头高度等。可以根据需求修改这些值来自定义 DataGrid 的样式。
